MACHINE FOR MAKING CONCRETE BLOCKS.

Specification of Letters Patent.

Patented March 16, 1909.

Application filed January 24, 1908. Serial No. 412,506.

To all whom it may concern:

Be it known that we, PETER WEoHr and JOHN WINFIELD, citizens of theUnited States, residing at F ostoria, in the county of Seneca and Stateof Ohio, have invented new and useful Improvements in Machines forMaking Concrete Blocks, of which the following is a specification.

This invention relates to machines for making concrete blocks. k

We desire to indicate that we use the terms concrete and block intheirbroad meanings. By concrete the substance not only thus specificallyknown, but equivalent substances or compositions, such as cement, formaking blocks of whatever form the latter may be.

We may make window sills, window caps, steps, building blocks, and otherarticles by the apparatus. acter that blocks of different sizes can bemade thereby, and these operations can be accomplished with ease andrapidity.

The apparatus is simple in construction and capable of readymanipulation.

In the drawings accompanying and forming part of this specification wehave" shown in detail one advantageous form of embodiment of theinvention which, to enable those skilled in the art to practice saidinvention, will be set forth in detail in the following description,while the novelty of the invention will be included in the claimssucceeding said description.

eferring tosaid drawings: Figure 1 is a perspective View of the machinewith the mold-box set up. Fig. 2 is a cross sectional view of the upperportion of the machine with the m0ldbox in knock-down condition. Fig. 3is a top plan view of the machine with %he parts occupying the positionshown in 1g. 1. view of the same, the boX being also set up. Fig. 5 is apers ective view of arock-shaft, actuating hand e, latches, and certaincooperating devices hereinafter more particularly described. Fig. 6 is aperspective view of an end and a supporting cross-bar therefor. Fig. 7is a like, view of a compound core, the parts thereof being separated.Fig. 8 is a top plan view of a modified form of core.

Like characters refer to like parts throughout the several figures ofthe drawings.

We prefer to provide a supporting frame for the mold-box and, while saidsupporting we intend to include he latter is of such char-' Fig. 4 is alongitudinal sectional frame may be of any desirable character, such aone as that illustrated particularly in Figs. 1 to {i of the drawings isadvantageous. This supporting frame involves in its makeup a skeletontop represented as consisting of the longitudinally-extending parallelside bars 2 and 3 and the end bars 4 and 5 joined together in anydesirable way so as to form a substantially skeleton or open structure.The structure just set forth is indicated as provided with severaldepending legs each designated by thenumeral 6 and WlilCh'GOllstitute aconvenient means for upholding said top or skeleton structure. Thesidebars 2 and 3 constitute in the present case supporting means for thecross-bars 7 and'8 which are connected by bolts or in any other suitablemanner with said side-bars.

The bolts connecting the cross-bar 7 with the side-bars 2 and 3 aredesignated by 9, and the crossbar 8 is connected 'to'the s de bars 2 and3 by bolts 10, the latter extending through longitudinally-disposedslots as 11 in the said side-bars 2 and 3, by virtue of which thecross-bar 8 can bemoved toward and from the companion cross-bar7 andlongitudinally of the sidebars 2 and 3 for the purpose of adjustment.The bolts 9 and 10 are equipped with the customary nuts and, prior toadjusting the cross-bar 8, the nuts of the bolts 10 are loosened, whenthe ad ustment can be easily accomplished and, when obtained, the nutsfor said bolts will be set up. To aid the nuts 0f the bolts 10 inretaining the adjustment of the cross-bar 8 we prefer to roughen theengaging faces of the cross-bar 8 and the side. orlongitudinallyextending bars 2 and 3, and this we may accomplish byproviding teeth, designated by 12 in each instance, on said engagingfaces.

To the cross-bar 7 is hinged a mold-box end 13, while to the cross-bar 8is hinged a substantially similar mold-box end 14. By virtue of thehinge connection the two ends can be separated from their cooperatingcross-bars. The bottom 15 of the mold-box is removably supported by thetwo cross-bars 7 and 8 and, when in operative position as shown in Fig.4, is inclosedby the lower portions of the two ends 13 and'14 and thesides 16 and 17. The side 1 6 is represented as hinged to alongitudinally-extending bar as 18 illustrated as sustained at itsopposite ends by the cross-bars igand 5. By virtue of the hingeconnection of the side It? with the bar 18 the two can be separated. Thebar 18 eXtends through longitudinall -disposed slots denoted in eachcase by 19 in the crossbars 7 and 8, as shown clearly in Fig. 1. Thislongitudinally-extending bar 18 is capable of adjustment transversely ofthe top of the frame. It may be fastened to the crossbars 4 and 5 bybolts as 20 shown as extending through longitudinally disposed slots as21 formed in said cross-bars 4 and 5. By tightening up the nuts of thebolts 20 the longitudinally-extending bar 18 can be maintained in anadjusted position and the bolts 20 may be aided in maintaining thisrelation by cooperating teeth as 22 formed respectively on thecross-bars 4 and 5 and bar 18.

The cross-bars 4 and 5 are represented as provided withbearings,designated by 23 in each case, to removably receive theopposite ends of a rock-shaft as 24 extending freely through openings orperforations in the cross-bars 7 and 8, by virtue of which the bar 8 canbe freely adjusted with respect to said rockshaft, whereby the lattercan be operated without affecting the said bars 7 and 8.

To the rock-shaft 24 are fastened in some suitable manner the twooutwardly-extending arms 25 which, when the mold-box composed of theseveral parts hereinbefore de scribed is in its operative relation orassem bled, stand vertically, as indicated in Fig. 1. In addition tosaid vertically-disposed arms 25, the rock-shaft 24 has fastened theretohorizontally-extending arms as 26 to which the mold bottom 15 may beremovably fastened. The mold-bottom is shown as equipped on its underside with ribs as 27 adapted for removable connection, for eX-' ample,by means of bolts as 28, with the arms 26, such bolts preferably passingthrough longitudinal slots in the ribs 27 and arms 26, respectively, soas to adapt said arms 27 to mold-bottoms of varying widths. The two arms25 are shown as connected by a bar as 29 upon which the mold-side 17 isadapted to rest, as clearly shown in Fig. 1.

It will be assumed that a mold-box of the size such as that shown inFig. 1 is being used and that the box is knocked down or collapsed, asshown in Fig. 2, preparatory to using a box which is longer and widerthan that illustrated. To use such a box the ends 13 and 14, the sides16 and 17 and the bot tom 15 will be dismounted, after which thecross-bar 8 will be moved away from the companion cross-bar 7 in themanner previously set forth; following this the longitudinallyeextendingbar 18 will be moved away from the shaft 24; or the order of procedurejust outlined may be varied as it is quite clear that we provide meansfor effecting the variation in size of the mold-box. We may readilyincrease the length thereof without affecting the width, or the widthcan be changed without affecting the length,

or both dimensions can be altered in a ready quick manner.

The side 16 is represented as provided near its top with alongitudinally-extending cleat as 30 the ends of which project beyondthe ends of said side 16 for engagement by gravity latches as 31connected with the rockshaft or pivot 32 for swinging movement, theengaging portions of the latches 31 and pro jecting ends of the cleat 30being notched. When the latches 31 are in engagement with the'projectingportions of the cleat 30 the mold-box consistin of the bottom, twosides, and ends will be he d in operative condition.

It will be assumed that the mold-box is set up as shown in Figs. 1, 3,and 4. In this condition the bottom 15 is connected with the rock-arms26 then horizontally-disposed and is inclosed by the lower portions ofthe ends 13 and 14 and the sides 16 and 17, the side 17 resting on thesupporting member 29. When the box is in such condition it can be filledwith cement or concrete up to the desired level and, when the mass inthe box has set or partially set, the latches 31 will be lifted. Theside 16 can then be dropped down, after which the same operation will befollowed with respect to the ends 13 and 14. Following this the shaft 24will be rocked to bring the side 17 to a horizontal position, and thebottom 15 to a vertical position. The side 17 can then be removed fromthe arms 25 and the molded block will go with it. A new side can besubstituted for that removed, or the block can be removed from the sidewhen the former has set. The shaft 24 is provided with some suitablemeans for effecting its operation by hand, and a lever as 33 may beprovided for this purpose.

We may, if desired, in forming a hollow block employ a core such as thatshown in Fig. 7 said core consisting of a body or main portion as 34 andan auxiliary portion as 35 both represented as cylindrical althoughtheir particular shape is not material. The end 14 is shown as having acircular hole 36 through which the main core section 34 can be passedfrom outside the mold-box, the operation continuing until the forwardend of the core portion 34 abuts against the mold end 13. The coreortion 34 may be provided with a hand e as 37 to facilitate itsoperation and it is also represented as having a circular opening 38entirely through the same to receive the transversely-disposed auxiliarycore portion 35 which, it will be understood, is of less diameter thanthe main core portion. The side 16 has a circular opening as '39 toreceive the auxiliary mold portion 35 which is put in place after themain portion is positioned, by passing said auXilary portion 35 throughthe opening 39 and then through the opening 38 until the inner orforward end of said mold ortion 35 abuts against the side 17, at whicfitime the mold-box can be filled with cement. mold portion 35 is providedwith a handle as 40 to facilitate its operation. I

We have shown as pivoted to the ends 13 and 14 core blocks designated by41 in each case and which are arranged to hug closely the main coreportion 35 near opposite ends j thereof and which form in the ends ofthe I block cavities. i

l-Ve show a modified form of core in Fig. 8 consisting of a main portionand an auxiliary portion 35 The core shown in Fig. 7, when the partsthereof are connected, is of approximately cruciform shape. The modiliedform of core illustrated in Fig. 8, however, is approximately of L-form.The core portion 35 removably ts the core portion 34 just as is the casewith the other form of core.

The various parts hereinbefore described may be made of wood, metal, ora coinbination of these materials, as deemed desirable or to meetparticular conditions.

It will be apparent from the foregoing description that we provide forthe adjustability of a moldbox. To adapt the latches 31 to theparticular size of the mold-box we prefer that said latches beadjustable of the shaft 32. This can be accomplished by having thelatches slide on the said shaft and in retaining them in theirrespective adjusted positions by means of pairs of collars as 31 l/Vehave fully described that form of embodiment of the invention which wehave selected for illustration in the drawings accompanying thisspecification and have also set forth two different forms of cores. Ifdesired, we may use the mold-box without any core or we may employ acore entirely different from either of the two shown. In like manner thelugs or blocks 41 may be of any I desirable form or shape. I11 somecases they I may, if desired, be wholly omitted. If del sired also wecan open and shut the moldbox with a lever or lever mechanism.

Other details may, if desired, be adopted within the scope of ourclaims.
